Last year, between August and November, 50 shakes were recorded.
The largest earthquake to strike portions of the NSW Hunter region in fifty years was one of August’s tremors.
At 12:02 p.m., a 5.0 magnitude earthquake rocked the town of Denman, sparking speculation that the activity was caused by nearby coal mining.
Stuart Clark, a geophysicist at UNSW, described the earthquake as “a little smaller than the Newcastle earthquake, and there was another one 5.3 (magnitude) in 1994.”
“Coal mining may have been the trigger, but compressional forces throughout the continent are the cause.”
